• Replacing a ten-year-old refrigerator bought in 1990 with a new Energy Star-qualified model would save enough energy to light the average household for three months and prevent more than 300 pounds of pollution each year, according to Energy Star.
• To minimize outgassing, choose models that have the least amount of plastic or rubber; opt for glass shelves and stainless steel.
• Your refrigerator uses the most electricity of all your kitchen appliances. It can account for as much as 15 percent of a home’s total energy usage, according to the Los Angeles Department of Water and Power.
• Top- or bottom- freezer models are more efficient–they use 7 to 13 percent less energy than side-by-side models.
• Automatic ice makers and through-the-door dispensers increase energy use by 14 to 20 percent.
• Models with an anti-sweat heater consume 5 to 10 percent more energy. Look for a model with an “energy saver” switch that allows you to turn off or turn down the heating coils that prevent condensation.
